There is overwhelming evidence that herbal based ingredients such as those found in NSL Moisturizer are beneficial for all skin types and anti wrinkle situations. However, as individuals, we all have different constitutions and sensitivities. No guarantees of any kind are made for the performance or effectiveness of the product. 

The great thing about it is that you get to try it during an introductory trial period. The worst that could happen, if you use it properly, is that you do not see your wanted results during the trial period. If this is the case then you can always contact customer service and obtain help in returning the product.
